You're doing everything right. You've been saving. You're watching rates. You've opened Zillow more times than you'd like to admit. But there's a quiet assumption underneath all of this that most first-time buyers don't notice until it costs them real money: that you know what you're doing. A Wells Fargo survey of 2,012 prospective homebuyers across the US found that assumption is wrong for most people, in very specific and very fixable ways. Three out of four respondents failed on core homebuying knowledge. The gaps weren't in things like cap rates or amortization. They were in basic process questions that come up in the first 60 days of any purchase.

Here are the questions the survey identified as problem areas, with the answers most buyers got wrong, and what the correct answer actually means for you.

The closing cost misconception: 90% got this wrong

The single largest knowledge gap in the Wells Fargo survey was closing costs. Ninety percent of respondents either didn't know what closing costs include, significantly underestimated the amount, or both.

Q: What is included in closing costs, and how much should you budget?
90% of survey respondents answered this incorrectly
Correct answer: Closing costs are the fees paid at the end of the transaction when ownership transfers. They typically run 2% to 5% of the loan amount. On a $350,000 mortgage, that's $7,000 to $17,500 in addition to your down payment. What's included: lender origination fees (often 0.5% to 1% of the loan), appraisal ($500 to $800), title search and title insurance ($1,000 to $2,000), homeowner's insurance prepayment (usually 12-14 months upfront), property tax escrow (2-3 months), recording fees, and attorney fees in states that require them. The buyer can negotiate with the seller to cover some or all closing costs, but this depends on market conditions. In a seller's market, asking for closing cost assistance weakens your offer.

The practical implication: if you've saved 5% for a down payment on a $350,000 home, you have $17,500 earmarked for the down payment. You may not have the additional $7,000 to $17,500 for closing costs. Many first-time buyers are shocked to learn they need significantly more cash than just the down payment. Budget for both from day one. The full closing cost breakdown covers each line item in detail.

Pre-approval vs. pre-qualification: the confusion that costs you offers

Q: What is the difference between mortgage pre-qualification and pre-approval?
68% of survey respondents used these terms interchangeably or defined them incorrectly
Correct answer: Pre-qualification is a quick estimate based on numbers you self-report. No documents are verified. No credit check is run (or only a soft pull is made). The number you get is not reliable and will not impress sellers. Pre-approval means the lender has pulled your credit, verified your income (W-2s, tax returns, pay stubs), verified your assets (bank statements), and issued a conditional commitment letter with a specific dollar amount. Pre-approval takes 1-3 business days and requires documentation, but it's what sellers and listing agents actually want to see. In competitive markets, many sellers won't even schedule a showing without proof of pre-approval.

If your offer letter says "pre-qualified," a listing agent in any reasonably competitive market will treat that as a weak offer. Get pre-approved before you start seriously touring homes, not after you've found one you want to make an offer on. Pre-approval letters are typically valid for 60 to 90 days, and you can get updated letters as rates or your search parameters change.

Contingencies: the clause 80% would skip

The statistic that should concern anyone entering this market: 80% of survey respondents said they'd submit an offer on a home without fully understanding what a contingency is or what happens if they need to use one.

Q: What is a contingency in a purchase offer, and what happens to your earnest money if you back out?
80% of survey respondents did not understand contingencies correctly
Correct answer: A contingency is a condition that must be satisfied for the sale to close. The three standard contingencies are: financing (your mortgage is approved), inspection (the home passes inspection or you approve the results), and appraisal (the home appraised at or above the purchase price). If you back out of a deal while a valid contingency is unmet, you typically get your earnest money returned in full. If you back out after waiving contingencies, or without a valid contingency reason, you typically lose your earnest money. Earnest money is usually 1% to 3% of the purchase price (on a $350,000 home, that's $3,500 to $10,500 at risk).

In competitive markets, buyers sometimes waive contingencies to strengthen their offer. Waiving the inspection contingency means you're accepting the property as-is. Waiving the appraisal contingency means you'll pay the purchase price even if the appraisal comes in lower (you make up the difference in cash). Never waive contingencies without fully understanding what you're giving up. Waiving the financing contingency when you're not 100% certain your loan will close can cost you your entire earnest money deposit if financing falls through.

What pre-approval doesn't guarantee

Q: Does pre-approval guarantee you'll get the mortgage?
54% of respondents believed pre-approval guarantees mortgage approval
Correct answer: No. Pre-approval is conditional, not final. The lender still needs to approve the specific property (appraisal, title search, condition of the home), verify your financial situation hasn't changed between pre-approval and closing, and complete underwriting. Common reasons mortgage loans fall apart after pre-approval: the appraisal came in below the purchase price; the buyer changed jobs or income dropped; the buyer opened new credit accounts or took on new debt; the title search found unresolved liens; or the property failed to meet lender requirements (condition, HOA issues, flood zone status). Keep your financial situation stable from pre-approval through closing: don't change jobs, don't open new credit lines, don't make large purchases.

What the home inspection covers (and what it misses)

Q: What does a standard home inspection cover, and what is excluded?
61% of respondents overestimated the scope of a standard inspection
Correct answer: A standard home inspection covers visible, accessible components: roof condition (from the ground or roofline, not always walked), foundation, exterior walls, windows and doors, HVAC systems (function-tested, not load-tested), electrical panels and wiring, plumbing (visible pipes and fixtures), insulation where accessible, and the attic and crawlspace if accessible. What it does NOT cover: septic systems (require a separate inspection), wells (require a separate water test), mold (visual signs only, not air quality testing), radon (requires a separate test), underground oil tanks, pest infestations (separate pest inspection in most states), pools or spas (separate inspection), chimneys (separate specialist), or anything hidden behind walls. The inspector is a generalist, not a specialist. If the inspector flags something, get a specialist quote before closing, not after.

Budget for additional specialized inspections based on the property. Radon testing runs $100 to $150 and is worth it in most of the Northeast and Midwest. Sewer scope costs $150 to $300 and is strongly recommended for homes older than 30 years. Pest inspection (termites, carpenter ants) varies by region but is often required by the lender anyway.

The down payment myth: what you actually need

Q: What is the minimum down payment required to buy a home?
47% of respondents believed you need 20% down to purchase a home
Correct answer: You do not need 20% down. Conventional loans allow as little as 3% down for qualifying first-time buyers. FHA loans allow 3.5% down with a credit score of 580 or higher. VA loans and USDA loans allow 0% down for qualifying borrowers. The catch at less than 20% down on a conventional loan: you pay private mortgage insurance (PMI), which typically costs 0.5% to 1.5% of the loan amount annually until you reach 20% equity. On a $350,000 loan with 5% down, PMI might add $150 to $350 per month. That's real cost, but it's often less than the opportunity cost of waiting years to save a full 20%. The full down payment guide covers the trade-off math.

The credit score question lenders don't volunteer

Q: How much does your credit score affect your mortgage rate?
73% of respondents knew credit score matters but couldn't quantify the rate impact
Correct answer: The rate difference between a 620 credit score and a 760+ credit score on a conventional 30-year mortgage is typically 0.5% to 1.5% in interest rate terms. At current rate levels near 6.52%, a borrower with a 620 score might be quoted 7.0% to 7.5%. A borrower with a 760+ score gets the headline rate. On a $350,000 loan, the payment difference between 6.52% and 7.25% is approximately $168 per month, or $60,000 over the life of the loan. The credit score and mortgage myth guide covers the specific score brackets and what to do if you're below 720.

The rate lock: when to use it

Q: What is a mortgage rate lock, and when should you lock?
69% of respondents didn't know they could lock a rate before closing
Correct answer: A rate lock is an agreement from your lender to hold a specific interest rate for a set period, typically 30, 45, or 60 days, while you complete the purchase. If rates rise during that period, your locked rate is protected. If rates fall, most standard rate locks don't let you take the lower rate (though some lenders offer "float-down" options for a fee). Rate lock timing: lock when you're under contract and confident in the property, not when you're just beginning your search. Locking too early (before finding a home) means the lock may expire, forcing you to re-lock at current rates. The typical purchase process from contract to closing takes 30 to 45 days, so a 45-day lock is the most common starting point.

PMI: the fee most buyers don't know they can cancel

Q: When does private mortgage insurance (PMI) end on a conventional loan?
82% of respondents didn't know PMI is cancellable
Correct answer: PMI on a conventional loan must be canceled by the lender when your loan balance reaches 78% of the original purchase price, under the Homeowners Protection Act. At 80% loan-to-value, you can request cancellation (the lender is not required to cancel automatically at 80%, only at 78%). This is based on the original purchase price, not the current market value. If your home appreciates significantly, you can request a cancellation based on a new appraisal showing 80% LTV on the current value, but the lender must approve this. Canceling PMI as soon as eligible saves hundreds per month. The PMI cancellation guide covers the exact steps to request it.

Earnest money: how much, and is it required?

Q: Is earnest money required, and how much is standard?
55% of respondents didn't know earnest money amounts are negotiable
Correct answer: Earnest money is not legally required in most states, but submitting an offer without it signals low commitment and will typically lose to competing offers. The standard amount is 1% to 3% of the purchase price, though in competitive markets 3% to 5% is increasingly common to strengthen an offer. The deposit is held in escrow by the title company or an attorney, not directly by the seller. Larger earnest money deposits signal seriousness and can sometimes compensate for a slightly lower offer price in a multiple-offer situation. Just ensure your contingencies are in place before putting a large deposit at risk.

The title search: why you need it even on a new build

Q: What does title insurance protect you against?
77% of respondents didn't understand what title insurance covers
Correct answer: Title insurance protects you against defects in ownership history that could threaten your right to the property. Examples: a previous owner had an undisclosed lien, an heir of a former owner claims they were owed part of the property, a forged signature somewhere in the chain of title, or an unpaid contractor placed a mechanic's lien. Title insurance is a one-time premium paid at closing, typically $500 to $1,500. There are two types: lender's title insurance (required by your mortgage lender, protects the lender) and owner's title insurance (optional but recommended, protects you). You want both. Even on a new construction home, the land underneath may have a title history with defects.

What to do with this list

The Wells Fargo survey found that the buyers who scored highest on process knowledge also made fewer expensive mistakes in their transactions, including fewer canceled contracts, fewer lost earnest money deposits, and fewer surprise cost shortfalls at closing. The knowledge gaps aren't hard to close. The concepts above aren't complex. They just require one afternoon of focused reading before you start making offers.

Here is the specific action sequence: get pre-approved (not pre-qualified) before starting serious property tours. Budget for closing costs at 3% of the loan amount as a conservative floor. Understand all three standard contingencies before signing an offer. Confirm your inspection includes the specific tests relevant to the property type and age. Know your credit score and what rate band it puts you in before talking to lenders.

The buyers who made costly mistakes in this market didn't lack motivation or discipline. They lacked information at the right moment. The good news is that none of these gaps require a real estate license to fill. You're already doing the reading. Most of the buyers in that survey weren't.
